EKD in the mud line – basic configuration


Basic configuration in the mud return line.

EKD in the mud line – basic & AAS


By disperse system of Mud canmultiphase proportions of dissolved and gaseous hydrocarbons are immediately detected at very low concentrations.The resolution is unsurpassed.

An option of the EKD system is the application of Acoustic Attenuation Spectroscopy (AAS).

Benefits:

-minimal Cost forHardware Option

-GUI for PC and SCADA Systems

liquid hydrocarbons

AAS real-time sonic log

EKD in the mud line – enhancement I


Solid and Cutting Separator Control Unit

Drilling fluid maintenance cost, clean up & dispositial cost as wellas the over all cost of boring, canbe reduced dramatucally when propersolids control techniques are utilized.

Several ultrasonic parameters are compared time range in a given in realtime. In case of differences that a defined predetermined range are larger can intervene in the process.

In large plants are several Detectors to be installed between the treatment stages.

Benefit:

-low cost version for lower pressure levels

-same Detectors
